Between 1974 and 1979 Mitsuru Fujita photographed mountains, fields, roads and abandoned sites along the Watarase River, on whose shores the Ashio Copper Mine disaster took place in the 1880s, leading to pollution of the areas around the Ashio copper mine and further downstream. In his imposing black-and-white photographs the mountain massif and the remnants of human activity appear as if evidence of a past fight between nature and humans, or as momentary extracts of deep time.
